Now's the season to start cooking Whole-Wheat Rigatoni with Butternut Squash and Beet Greens. I was thinking of this recipe last night as I made a pumpkin gratin (yum!) and realizing how much I like to cook with fall ingredients. I also roasted a beet and grated it atop some greens I dressed with a mustardy vinaigrette to top off the fall/winter feel of the meal.
